A bottle stopper mainly includes a body, a plug and a jacket. The body has an expansion spread by the plug and outwardly confronting with the jacket. The plug comprises two necks for two different engagements alternatively engaged with the body to provide a locking means and a resealing means for bottle neck. The body is structurally retained between the plug and the jacket being assembled as a unit to form the bottle stopper. When the bottle stopper is initially inserted into a bottle neck and pressed to position at the first engagement, the locking means provides a maximum expansion to lock around the bottle neck. And it has an appearance and a function of indicating whether the bottle neck has previously opened or the stopper has been used. When the bottle stopper is pressed downward positioning at the second engagement, the resealing means provides a slightly expansion for allowing to initially release and reseal the bottle neck.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention is related to a bottle stopper for conveniently inserting into bottle neck, completely sealing it and preventing from unlawful reuse in closing process, and more particularly to the bottle stopper for using to reseal bottle neck opened.

2. Description of the Related Art

Liquor, wine or the like is conventionally contained in glass or ceramic bottle. Before the bottling process, distilled heat liquor has already situated in high inner pressure. In the bottling process, when the traditional plug is typically forced into the neck of a filled bottle, the inner pressure in the filled bottle is essentially greater than atmospheric pressure. Typically, the diameter of plug is apt to slightly greater than the inner circumference of the bottle neck in order to sealably confront each other when the plug is axially inserted into the bottle neck. The plug, therefore, is capable of withstanding substantial inner pressure over long storage periods without deterioration or effect on the contents. During the bottling process, it is hard while the plug is inserted as intended into the bottle neck. In particular, the plug is hard to be remained in the bottle neck by an axially directed inner pressure from within the bottle.

The conventional plug is made of cork which has capillary. The inner pressure from within the bottle, thus, will be released through the capillary of the cork during closing bottle process so that the plug has an improved seal in the bottle neck. However, the plug necessitates to tightly seal the bottle neck and thus it is hard to be inserted into the bottle neck in the bottling process. In addition, wet and aged cork tends to disintegrate and it is often difficult to remove from the bottle neck. Accordingly, it is inconvenient to remove the cork when it is easily snapped in two.

There is a serious problem in the market. Illegal factories fabricate fake liquor or wine by using the used bottles and plugs on which covering a new and intact cap of tinfoil or a plastic material. Accordingly, there is a need of performing the function of indicating whether or not the bottle has previously been opened. Therefore, preventing from reusing plug is one of solutions.

Applicant's PCT application serial No. PCT/US00/28866 discloses a bottle plug mainly including a bottle plug member and an elastomer member. The bottle plug member consists of a gas-tight means and a reuse-proof means and further inserts into the elastomer member being assembled as a unit to form the bottle plug. When the bottle plug is inserted into a bottle neck, the gas-tight means provides an expansion portion to seal the bottle neck and the reuse-proof means provides an appearance and the function of indicating whether the bottle neck has previously opened or the bottle plug has been used. The used bottle plug cannot employ again to reseal a bottle neck even though it can prevent from unlawful reuse in bottle closing process. However, such bottle plug's elements cannot be made of glass, crystal, ceramic or manufactured various designs of bottle head.

The present invention intends to provide a bottle stopper including a locking means and a resealing means in such way to as to mitigate and overcome the above problems.

SUMMARY OF THE INVENTION

The primary objective of this invention is to provide a bottle stopper with two expansion portions for forming a locking means and a resealing means in bottle neck, which is particularly capable of reusing the used bottle stopper after initially released.

The secondary objective of this invention is to provide a bottle stopper with an obstructer which can prevent from an accidental press of a plug.

The further objective of this invention is to provide a bottle stopper with a head portion which can be made of various kinds of material and designed various preferred shape.

The present invention is the bottle stopper which mainly includes a body, a plug and a jacket. The body has an expansion spread by the plug and outwardly confronting with the jacket. The plug comprises two necks for two different engagements alternatively engaged with the body to provide a locking means and a resealing means for bottle neck. The body is structurally retained between the plug and the jacket being assembled as a unit to form the bottle stopper. When the bottle stopper is initially inserted into a bottle neck and pressed to position at the first engagement, the locking means provides a maximum expansion to lock around the bottle neck. And it has an appearance and a function of indicating whether the bottle neck has previously opened or the stopper has been used. When the bottle stopper is pressed downward positioning at the second engagement, the resealing means provides a slightly expansion for allowing to initially release and reseal the bottle neck.

DETAILED DESCRIPTION OF THE INVENTION

Referring to FIG. 1, a bottle stopper in accordance with a first embodiment of the present invention mainly includes a body generally designated as numeral 1, a plug as numeral 2 and a jacket as numeral 3. Referring to FIGS. 1 and 2, the body 1 is made of plastic material and includes an opening 15 formed on its top and a plurality of flexible walls 12 projected downward from the top and encircled an axis to define a space with an opening 11. The inner circumference of each flexible wall 12 provides a slightly protrusion 14 projecting inwardly in a common plane perpendicular to the axis defined by the body 1. The outer circumference of each flexible wall 12 further provides a plurality of screwing ribs 13 projecting outwardly and encircling co-axially around the axis of the body 1. The plug 2 is essentially consisted of a head 20 and a leg 21 combined by adhesive. The head is made of crystal, glass, ceramic or the like. The preferred shape of the head 20 is dictated somewhat by tradition and etiquette. The rod-shaped or cannular leg 21 is confined within contours of the inner circumference of the body 1. The leg 21 provides a first neck 22 to form a locking means and a second neck 23 with a smaller diameter relative to the first neck 22 to form a resealing means. The two necks 22 and 23 are co-axially juxtaposed in serious along the axis of the leg 21 so that the plug can be pressed downward to change the locking status to resealing status. The two necks 22 and 23 are adapted to be engaged with the protrusion 14 of the body 1 to provide two diametrically different protrusions of the bottle stopper when the leg 21 is inserted into the space formed by the flexible wall 12. The leg 21 cannot be released from the body 1 for taking apart, when the protrusion 14 is engaged with either the neck 22 or 23. The neck 22 has a slightly inclined surface 221 projected in a common conical surface defined by the axis of the leg 21 and a perpendicular surface 222 relatively perpendicular to the axis of the leg 21. By contrast, the neck 23 just has two perpendicular surfaces 231 and 232 sectioning the leg 21. The protrusion 14 has an inclined surface 141 conforming with the inclined surface 221 of the neck 22 for easily sliding so that the neck 22 of the plug 21 can be conveniently pressed to engage with the protrusion 14 of the body 1. In order to prevent the leg 21 relatively rotating to the body 1, the initial end of the cross section of the leg 21 forms a square confined within the opening 15 of the body. In addition, the plug 2 has an annular wall 25 formed from a common plane and projecting along the axis of the leg 21. The jacket 3 may be made of cork, foamed plastic material, compressible material or the like which cannot chemically contaminate the content within the bottle giving it a distressing taste and permits only a miniscule amount of air to enter the bottle as well as breathing. The jacket 3 is cup-shaped part with a cavity in which adapted to receive the combination of the body 1 and the plug 2 co-axially aligned to it. The inner circumference of the jacket 3 includes a plurality of grooves 31 encircling co-axially around its axis correspondingly engaging with the ribs 13 of the body 1 and a plurality of elongate ribs 32 parallel to its axis for precluding relative movement between the body 1 and the jacket 3. It is convenient to insert that the outer diameter of the jacket 3 is slightly less than the inside bottle neck diameter. The outer circumference of the jacket 3 with two different diameters corresponding to the expansion portion of the body 1 is adapted to securely confront the inner circumference of the bottle neck for locking and resealing. It is desirable that the body 1 and the jacket 3 can be formed as a singular member in molding process. In order to improve the sealing effect of the bottle stopper, a plurality of regularly spaced annular ribs 33 raises with respect to a cylindrical outer surface of the jacket 3 for intimately confronting with the inner circumference of the bottle neck.
